We do this type of directed phishing attack all the time for our
global clients. Instead of having an automated MITM we have scripts
that alert us when a user visits the site and we login to the real
site once we recieve the first token code. Then wait as the user
submits the second code and your in..
The only protection mechanism that helped out was digital client
certs. But we still got into citrix and performed a local priv
escalation essentially controlling the internal domain. So 2 factor
authentication isn't enough. Or in my mind. 2Factor auth doesn't
protect a user much more than static passwords.
It's all about userAwareness and Incident Response.
